Compress PDF
Make heavy scanned PDFs small enough to email or upload.
How to use it
- Add your file. Drop it on the box above or tap it to pick it from your device.
- Choose and run. Pick the sharpness (150 is a good balance), then drop the PDF.
- Download. Press Download. Nothing was uploaded, so nothing is stored anywhere.
What it does
Each page is redrawn at the sharpness you pick and saved as a compressed picture in a new PDF. Scans from phones and scanners often drop by 70 to 90%.
When to use it
Upload forms with a size limit, emailing scanned documents, and phone scans that came out tens of megabytes.
Private by design
Most online tools upload your file to their servers. This one doesn't: it loads into your browser and does the work on your own phone or computer, so your files never leave it.
Questions
Is this compress pdf free?
Yes, completely free, with no account, no watermark and no daily limit.
Are my files uploaded?
No. Everything happens inside your browser on your own device. Nothing is sent to us or anyone else.
Does it work on iPhone and Android?
Yes, in Safari, Chrome and other modern browsers.
Does it work with password-protected PDFs?
No. Remove the password with the app that made the PDF first; this tool can't open locked files.
Will text stay selectable?
No. This method redraws pages as pictures, which is what shrinks scanned PDFs. Keep the original if you need to copy text.
